What are Aetna breast reduction requirements?

I have had similar problems with Aetna.  If you don't want to be too small consider paying out of pocket.

These issues differ by region, where each insurance company can demand different amounts of breast tissue. In my area, Aetna sometimes wants twice as much breast tissue taken as the other insurance companies. I counsel my patient to either switch insurance companies, if I feel they will be able to be covered under a different insurance provider, or to pay for the procedure out of pocket. This allows the surgeon to focus on making the breasts match with your chest wall and to give you a great result and not to be constrained by an insurance mandated number. If your surgeon does not feel they will be able to leave you with adequate breast tissue then you should not undergo a reduction through insurance.

Some insurance companies use the Schnur sliding scale based on body surface area, calculated on your height and weight.   Aetna has their own sliding scale which requires more from smaller patients relative to the Schnur scale, but maxes out at 1000 gms per breast.  Other just require 500 grams no matter what your height and weight.  And if you are in Canada the surgeon decides.  In this age of increasing out of pocket expenses and deductibles seek out a board certified plastic surgeon who will do it as a cosmetic procedure.  Sometimes you end up saving money and you can dictate your cup size .  Regards.
